I have about 5 outdoor toads living on my back porch. Some of them are big and the others are quite small. I think some of them are hungry, I was wondering what I can do to help them get food or if there is anything I may have in my home that I can lay out for them. Any suggestions? Oh and what happens to them in the winter? Thanks for any help!

I have an Idea Antimatter is an unstable material but if harnessed it could be used for space exploration. I think if we could create a controled reaction of antimatter and matter (yes like in Star Trek) and somehow transfer that kenitic energy into electricty wich then would be sent to powercells into an engine we could dramaticly cut the travel time in space from Hundreds of years into months, days and weeks. THe only problem is that Antimatter is not found on earth One milligram is worth #300 Billion Dollars. Also if we brought it to Earth it would have to be contained so secruely because if it isnt the violent reaction when the antimatter hit matter it would destroy Earth.

15. Geometry. A homeowner wishes to insulate her attic with fiberglass insulation to
conserve energy. The insulation comes in 40-cm wide rolls that are cut to fit between
the rafters in the attic. If the roof is 6 m from peak to eave and the attic space
is 2 m high at the peak, how long does each of the pieces of insulation need to be?
Round to the nearest tenth.

16. Geometry. For the home described in exercise 15, if the roof is 7 m from peak to
eave and the attic space is 3 m high at the peak, how long does each of the pieces
of insulation need to be? Round to the nearest tenth.

Ceres is by far the largest asteroid. Its diameter is almost twice the size of the diameter of the second largest asteroid, and its mass is more than 1/3 the total mass of all the asteroids in the asteroid belt.

It seems highly improbable for Ceres to be so disproportionately larger than the millions of other asteroids in the asteroid belt. Did Ceres win the lottery, or it there a theoretical explanation as to why it is so much larger?

OK, keep it simple!!!!
Pi is an infinite series of numbers, but it never reaches 3.15
A Third as a decimal (is this just a problem of the base 10 system?)
Think of a number, then add 1
